In a network with a backbone, it is important to find the route that is the shortest distance between the source and the destination. In a wireless network, how does it function with clients that have restricted mobility? Explain in detail.

What does a router perform for a network, exactly? Please include at least four salient aspects or traits.

In a Ring topology based network, each node is connected to the two nearest node so that the entire network forms a circle. How do messages travel through the network? Messages travel from one device to the next until they reach the destination device Messages are sent to a central device that forwards them to the destination devices. Messages are sent directly to the destination devices only. Messages are sent to all devices connected to the network.

Ethernet is a distributed LAN protocol, which means that there is no centralized control node, and therefore a single node's failure will never bring the whole network down. However, can you see any advantage in establishing a centralized LAN in which a single node is in charge of the whole network and determines who receives messages and who waits? Explain.
